When you attach instances, Amazon EC2 Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds t

Gets information about the scheduled actions that haven't run or that have not reached their end time. To describe the scaling activities for scheduled actions that have already run, call the DescribeScalingActivities API.

Describes the specified tags. You can use filters to limit the results. For example, you can query for the tags for a specific Auto Scaling group. You can specify multiple values for a filter. A tag must match at least one of the specified values for it to be included in the results. You can also sp

Describes the termination policies supported by Amazon EC2 Auto Scaling. For more information, see Configure termination policies for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

Gets information about the traffic sources for the specified Auto Scaling group. You can optionally provide a traffic source type.

Detaches one or more traffic sources from the specified Auto Scaling group. When you detach a traffic source, it enters the Removing state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the traffic source using the DescribeTraffic

Disables group metrics collection for the specified Auto Scaling group.

You can view group metrics using the Amazon EC2 Auto Scaling console or the CloudWatch console. For more information, see

Moves the specified instances into the standby state. If you choose to decrement the desired capacity of the Auto Scaling group, the instances can enter standby as long as the desired capacity of the Auto Scaling group after the instances are placed into standby is equal to or greater than the minim

Executes the specified policy. This can be useful for testing the design of your scaling policy.

Moves the specified instances out of the standby state. After you put the instances back in service, the desired capacity is incremented. For more information, see Temporarily removing instances from your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

This restores your Auto Scaling group to the configuration that it was using before the start of the instance refres

Sets the size of the specified Auto Scaling group. If a scale-in activity occurs as a result of a new DesiredCapacity value that is lower than the current size of the group, the Auto Scaling group uses its termination policy to determine which instances to terminate.
